Version 2 of the Secwepemc dictionary was printed with additions to the Kuipers dictionary. Many elders. language students and Secwepemc people worked in compiling version 2. This was done with the help of Dr. Dwight Gardiner and Secwepemc elders and language speakers. This version also produced a Word-List with 500 additions.

The dictionary was put together by Mona Jules and Dr. Strang Burton.
